Method | Observer 1 | Observer 2 | ∆ | TEM (%) | SEE | ICC (95% CI) | Classification |
---|---|---|---|---|---|---|---|
mean 2D:4D (SD) | mean 2D:4D (SD) | ||||||
X-ray | 0.905 (0.020) | 0.904 (0.020) | 0.001 | 0.007 (0.9%) | 0.010 | 0.94 (0.91-0.96) | excellent |
DXA | 0.908 (0.019) | 0.907 (0.020) | 0.001 | 0.009 (1.2%) | 0.010 | 0.90 (0.86-0.94) | excellent |
Note: Interrater reliability for both observers. = difference; TEM = technical error of measurement, absolut and in % of the mean. SEE = standard error of estimate; ICC = intraclass correlation coefficients; CI = confidence intervall; classification according to Rosner (2011). ICCs < 0.7 were considered non-acceptable, 0.71 < ICCs < 0.79 were acceptable, 0.80 < ICCs < 0.89 were very good and ICCs >0.90 were excellent.
